A reduced simulation applied to viscoelastic fatigue of polymers using a time multi-scale approach based on Partition of Unity method
Sebastian Rodriguez, Angelo Pasquale, Jad Mounayer +5
The simulation of viscoelastic time-evolution problems described by a large number of internal variables and with a large spectrum of relaxation times requires high computational r…
Modular parametric PGD enabling online solution of partial differential equations
Angelo Pasquale, Mohammad-Javad Kazemzadeh-Parsi, Daniele Di Lorenzo +3
In the present work, a new methodology is proposed for building surrogate parametric models of engineering systems based on modular assembly of pre-solved modules. Each module is a…
A time multiscale based data-driven approach in cyclic elasto-plasticity
Sebastian Rodriguez, Angelo Pasquale, Khanh Nguyen +2
Within the framework of computational plasticity, recent advances show that the quasi-static response of an elasto-plastic structure under cyclic loadings may exhibit a time multis…
A time multiscale decomposition in cyclic elasto-plasticity
Angelo Pasquale, Sebastian Rodriguez, Khanh Nguyen +2
For the numerical simulation of time-dependent problems, recent works suggest the use of a time marching scheme based on a tensorial decomposition of the time axis. This time-separ…
